Back

A wave is a disturbance that transfers energy from one place to another.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium and can travel through a vacuum.

Front

What is the relationship between frequency and wavelength?

Back

Higher frequency means shorter wavelength, and lower frequency means longer wavelength.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance the wave moves from its rest position.
